【必見】Claude Codeが巨大コードベースで効く理由！agentic searchとハーネス7要素を徹底解説

In this video, we explained the Anthropic official blog post, "Why Claude Code Works in Huge Codebases." We covered the mechanism of sequentially searching for necessary information using agentic search rather than pre-indexing or RAG, how Claude harnesses such as CLAUDE.md, hooks, skills, plugins, MCP, LSP, and subagents influence results as much as the model, and even summarized operational points regarding design and organizational implementation to prevent context rot. What harnesses have you been creating recently?
